Separating the alter operation in two will result in upgrade running twice as slow, because it will rebuild the table twice instead of once.

But per Tims comment (which I agree with, as it seems very strange/borderline) (In reply to comment #13) I think this is too broken to bother trying to fix on our side. We must have loads of patches that add indexes on new columns. I can't believe that 1.17 is the first major version that doesn't work on MySQL Cluster. Lowering priority. Certainly, I personally can't see any issue just changing the db patch per the above patch, as it shouldn't cause any more issues -- Configure bugmail: https://bugzilla.wikimedia.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug.

I reproduced it under gdb with debugging symbols, and I've isolated it to some
extent. The bug occurs when an index is added to a new field, i.e. a field
added in the same ALTER TABLE.
In sql_table.cc near line 6010:
/* Key not found. Add the offset of the key to the add buffer. */
ha_alter_info-index_add_buffer
[ha_alter_info-index_add_count++]=
new_key - ha_alter_info-key_info_buffer;
key_part= new_key-key_part;
end= key_part + new_key-key_parts;
for(; key_part != end; key_part++)
{
/* Mark field to be part of new key */
if ((field= table-field[key_part-fieldnr]))
field-flags|= FIELD_IN_ADD_INDEX;
new_key-key_part-fieldnr appears to be a field index in the new table, but
it's used to attempt to fetch field information from the old table.
(gdb) print *new_key
$30 = {key_length = 32, flags = 40, key_parts = 1, extra_length = 0,
usable_key_parts = 2, block_size = 0,
algorithm = HA_KEY_ALG_UNDEF, {parser = 0x0, parser_name = 0x0}, key_part =
0x78a26208,
name = 0x78a22f50 cl_collation, rec_per_key = 0x0, handler =
{bdb_return_if_eq = 0}, table = 0x0}
(gdb) print *key_part
$31 = {field = 0x0, offset = 751, null_offset = 0, length = 32, store_length =
0, key_type = 1,
fieldnr = 5, key_part_flag = 0, type = 0 '\000', null_bit = 0 '\000'}
(gdb) print key_part-fieldnr
$15 = 5
(gdb) print table-field[0]-field_name
$33 = 0x78a24599 cl_from
(gdb) print table-field[1]-field_name
$34 = 0x78a245a1 cl_to
(gdb) print table-field[2]-field_name
$35 = 0x78a245a7 cl_sortkey
(gdb) print table-field[3]-field_name
$36 = 0x78a245b2 cl_timestamp
(gdb) print table-field[4]-field_name
Cannot access memory at address 0x30
(gdb) print table-field[5]-field_name
warning: can't find linker symbol for virtual table for `Field' value
warning: found `Field_longlong::~Field_longlong()' instead
$37 = 0x778ff544
UH\211\345SH\203\354hH\211}\250H\211u\240\211U\234dH\213\004%(
table-field[5] points into arbitrary memory, and so the attempt to write to
table-field[5]-flags causes a segfault.
I'll add this to the MySQL bug once dev.mysql.com stops timing out.
